All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart illustrating a channel selection method according to an embodiment of the present invention.
An embodiment of the present invention provides a channel selection method, including:
s10, acquiring scene parameters of the alternative channel and the current application scene; wherein the scene parameters include: interference parameters and environmental parameters.
The method for acquiring the alternative channel comprises the following steps: and scanning wireless indexes of different channels and scoring each channel. And selects the candidate channels m-first ranked. In this embodiment, when the difference value between the highest score and the lowest score of each channel rank does not exceed the first threshold, all channels between the highest score and the lowest score may be selected as candidate channels. Thereby ensuring that the finally selected channel is a qualified channel. It is understood that the first threshold may be set by the user, and is not limited herein.
It should be noted that the radio indicator is an interference parameter, and the interference parameter includes: the method comprises the following steps of (1) the number of base station equipment, the comprehensive noise fraction of a communication network system, a channel interference threshold value, channel occupancy rate, a frame detection sequence and link layer link rate; further, the method can be expanded to space channel estimation interference, interference adjustment, transmission power, background noise and the like. The channel can be scored by each interference parameter. The environmental parameters include: temperature parameters, humidity parameters, and the like.
And S20, determining the corresponding channel sensitive condition according to the scene parameters of the current application scene and the internet access situation of the current user.
The internet surfing condition of the user comprises the following steps: the method comprises the steps that a user plays games by using a mobile phone or a computer, the user downloads services, the user carries out voice and video calls, the user carries out network television services, and the distance between a user terminal and a signal source (a router) is far.
It should be noted that, because the scene parameters include the interference parameters and the environmental parameters, and also need to be combined with the internet access situation of the current user, at least one channel sensitive condition is obtained, so that the criteria for selecting the channel are diversified.
Specifically, after the scene parameters are calculated, the user autonomously reports the internet access condition required by the user, and the control end of the communication device determines the corresponding channel sensitive condition according to the scene parameters and the reported internet access condition. It can be understood that a user can report the internet surfing condition through the APP connected with the communication equipment; the selection can also be performed through keys on the communication equipment, for example, a plurality of keys are arranged on the communication equipment, and each key corresponds to one internet surfing condition; the internet surfing condition can also be selected through a display screen on the communication equipment.
S30, selecting the best channel corresponding to the current application scene according to the signal quality parameter of each candidate channel and the channel sensitive condition.
Wherein the signal quality parameters include: signal delay, signal peak, signal strength, and signal throughput. The corresponding channel sensitive conditions include: delay sensitive conditions, peak sensitive conditions, throughput sensitive conditions, and signal strength sensitive conditions.
Specifically, since the weights of the signal quality parameters are judged according to the channel sensitive conditions, each candidate channel is better evaluated, and thus the optimal channel is selected in the current scene.
In summary, by acquiring the scene parameters of the candidate channel and the current application scene, determining the corresponding channel sensitivity condition according to the scene parameters of the current application scene and the internet access situation of the current user, and then processing the signal quality parameter of the candidate channel according to the channel sensitivity condition, the optimal channel corresponding to the current application scene is selected from the candidate channels. From the above analysis, it can be known that the channel sensitivity condition is determined from multiple aspects according to the internet access condition of the current user by considering the scene parameters, so that the channel selection criterion is diversified, and therefore, a suitable channel can be selected in different scenes, and the user experience is improved.
As a modification of the above, after step S30, the method further includes:
and S40, forming a template by the scene parameters and the optimal channel corresponding to the scene parameters, and storing the template in a preset template library. The preset template library comprises a plurality of different scene parameters and optimal channels corresponding to the scene parameters, so that the optimal channels can be obtained in the template library when the scene parameters are obtained. It should be noted that, if the user is not satisfied with the currently selected best channel, the calculation is performed again according to that the current scene is that no similar scene exists in the template library.
Specifically, since the scene parameters and the optimal channel corresponding to the scene parameters are stored in the preset template library, when the scene parameters similar to the scene parameters exist next time, the optimal channel is directly extracted from the template library, so as to improve the user experience.
As an improvement of the above scheme, the acquiring of the scene parameter of the current application scene specifically includes:
and S100, distributing the interference parameters and the environment parameters according to preset weights to form a scene feature vector of the current application scene.
In the present embodiment, the scene feature vector is defined as follows:
wherein alpha istIs a weight, ntAs an interference parameter, otIs an environmental parameter. The weights of the interference parameters may be based on the weights in the factory automated channel selection algorithm. Generally, the weight of the interference parameter is greater than the weights of the other parameters.
In another preferred embodiment, the scene parameters include: an interference parameter, a time parameter, and the environmental parameter; it should be noted that when any parameter is added to the application scene parameters, the application scene parameters are distributed according to a preset weight to obtain the scene feature vector.
As an improvement of the above scheme, scene parameters of an alternative channel and a current application scene are obtained; wherein the scene parameters include: after the interference parameter and the environmental parameter, before determining a corresponding channel sensitive condition according to a scene parameter of a current application scene and an internet access situation of a current user, the method further comprises:
and S11, judging whether a similar scene of the current scene exists in a preset template library.
Specifically, whether a similar scene of the current scene exists in a template library is judged according to scene parameters.
In this embodiment, the scene parameters and the scene parameters in the template library are calculated by the euclidean distance. And when the calculated distance is smaller than a second threshold value, the two scenes are considered to be similar. The second threshold may be set as needed, and is not limited herein. Similar scenes can also be calculated by methods such as SVM (support vector machine), BP (back propagation) and the like.
Euclidean distance calculation formula:
and S12, in response to the judgment result that the similar scene of the current scene does not exist, determining the corresponding channel sensitive condition according to the scene parameters of the current application scene.
Specifically, when the calculated distance is greater than the second threshold, it indicates that a similar scene of the current scene does not exist in the template library, and the corresponding channel sensitive condition is determined according to the scene parameter of the current application scene.
As an improvement of the above solution, after determining, in response to the determination result that there is no similar scene of the current scene, a corresponding channel sensitive condition according to a scene parameter of the current application scene, the method further includes:
and S13, in response to the judgment result that the similar scene of the current scene exists, extracting the optimal channel corresponding to the similar scene from the preset template library to serve as the optimal channel of the current scene.
Specifically, when the calculated distance is less than or equal to the second threshold, it indicates that a similar scene of the current scene exists in the template library, and then the optimal channel corresponding to the similar scene is extracted from the preset template library.

referring to fig. 2, S200, it is determined whether the environmental parameter satisfies a preset environmental comfort condition.
The preset environment comfort conditions comprise that the temperature of the current environment does not exceed a third threshold and the humidity does not exceed a fourth threshold.
And S201, in response to the judgment result that the preset environment comfort condition is met, determining a corresponding channel sensitive condition according to the internet surfing condition of the current user.
It can be understood that if the current environment meets the comfort condition, that is, the environment parameter does not affect the internet access situation of the user, the corresponding channel sensitive condition is determined only according to the internet access situation of the user.
Illustratively, if the user is playing a game using a cell phone or computer at the time, it is desirable to avoid the occurrence of high latency. Then a delay sensitive condition is corresponded to.
If the user is currently downloading traffic, a higher download peak is needed. This corresponds to a peak sensitive condition.
If the user is performing a voice video call or an internet protocol television service at this time, it is necessary to maintain good call quality and a clear screen. This corresponds to a throughput sensitive condition.
If the user is at a longer distance from the signal source (i.e., the router), a radio signal with a stronger signal strength is required. This corresponds to a signal strength sensitive condition.
And S202, in response to the judgment result that the preset environment comfort condition is not met, determining a corresponding channel sensitivity condition according to the internet surfing condition of the current user, and determining the corresponding channel sensitivity condition according to the environment parameter.
Specifically, when the temperature or the humidity is greater than the corresponding threshold, the environmental factors may affect the internet access situation of the user, and the sensitive condition of the channel may also change. The channel selection criterion is diversified, so that a proper channel can be selected under different scenes, and the user experience is improved.
Illustratively, if the user's router is located in the living room, the television is also in the living room, and the user's bedroom is further from the living room. Under the condition of relatively proper temperature, a user may stay in a living room for a long time to watch the network television, and at the moment, a throughput sensitive condition is selected; in cold conditions with lower temperatures, a user may be in a bedroom for a longer time, playing a mobile game or watching a flat video, and then the signal strength sensitive condition and the delay sensitive condition need to be selected simultaneously. Under the condition that the humidity exceeds the threshold value, a user may have a bath right after taking a bath, and then the electric hair drier is turned on, strong electromagnetic interference may occur in some 2G frequency bands, the signal intensity may be affected, and a signal intensity sensitive condition needs to be selected.
As an improvement of the above scheme, the scene parameters further include: a time parameter.
Correspondingly, the determining the corresponding channel sensitive condition according to the scene parameters of the current application scene and the internet access situation of the current user includes:
and judging the time interval corresponding to the current time parameter.
And determining the corresponding channel sensitive condition according to the time interval.
Specifically, the services performed by the users in different time periods may be different, for example, the users may perform downloading services during the daytime, and the requirement on the data transmission rate is relatively high; the game service can be performed at night, and the game service is more sensitive to factors such as time delay, packet loss and the like. Thus, when the time parameter is in the time interval of the day, the peak sensitive condition is selected. When the time parameter is in the night time interval, a delay sensitive condition is selected.
As an improvement of the above scheme, the selecting an optimal channel corresponding to the current application scenario according to the signal quality parameter of each candidate channel and the channel sensitive condition specifically includes:
referring to fig. 2, S300, weights of the signal delay, the signal peak, the signal strength, and the signal throughput of an alternative channel are determined according to the sensitive condition.
Specifically, the signal delay, the signal peak value, the signal strength, and the signal throughput of the candidate channel are obtained by the communication device, and then the corresponding sensitive condition is determined according to different scenarios, that is, if the delay sensitive condition is selected, the weight of the signal delay is increased. If a plurality of signal sensitive conditions are selected, the weights of the corresponding signal quality parameters are increased respectively. The setting of the weight may be performed according to a large number of experiments, or may be performed according to the user's needs.
And S301, calculating the score of each alternative channel according to the signal delay, the signal peak value, the signal strength and the weight of the signal throughput, and selecting the alternative channel with the highest comprehensive score as the optimal channel corresponding to the current application scene.
Specifically, the signal delay, the signal peak value, the signal strength and the signal throughput are respectively scored, and then comprehensive scoring is performed according to the weight, so that the score of each alternative channel is obtained, and the alternative channel with the highest comprehensive score is used as the optimal channel corresponding to the current application scene.
